AWS::Events::EventBus

Creates a new event bus within your account. This can be a custom event bus which you can use to receive events from your custom applications and services, or it can be a partner event bus which can be matched to a partner event source.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON

{
  "Type" : "AWS::Events::EventBus",
  "Properties" : {
      "EventSourceName" : String,
      "Name" : String
    }
}

YAML

Type: AWS::Events::EventBus
Properties: 
  EventSourceName: String
  Name: String

Properties

EventSourceName

If you are creating a partner event bus, this specifies the partner event source that the new event bus will be matched with.

Required: No

Type: String

Minimum: 1

Maximum: 256

Pattern: aws\.partner(/[\.\-_A-Za-z0-9]+){2,}

Update requires: Replacement

Name

The name of the new event bus.

Event bus names cannot contain the / character. You can't use the name default for a custom event bus, as this name is already used for your account's default event bus.

If this is a partner event bus, the name must exactly match the name of the partner event source that this event bus is matched to.

Required: Yes

Type: String

Minimum: 1

Maximum: 256

Pattern: [/\.\-_A-Za-z0-9]+
